Self-programming
As car technology has evolved throughout the years, ignition keys have evolved too. Gone are the days of simple mechanical-only keys that could be manufactured at a hardware store for under $10. The latest models are equipped with computers that have improved anti-theft security. The cars require a transponder chip-integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly.
There are many kinds of car key programming that can be done by locksmiths who are professionals. Some are complex and require advanced tools. These tools are not available to the general public and are used only by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other kinds of key programming can be done by anyone. They are typically done using the onboard diagnostics port, which is accessible with the key-fob-programming device. This procedure can be carried out by a locksmith who is trained with the help of an online guide or the car's owner's manual.

You can be assured that the new key will function and is programmable for your car. You'll have to pay the dealer for programming and replacement keys if you do not.
Key Programmers
Modern vehicles require a key-programming method to start the vehicle's system and to start the car. In certain instances the key will have to be programmed by an auto locksmith or a dealer. The key may not work correctly or will not start the vehicle at all. The reason for this is that the new key has not been programmed into the vehicle's system. This can be quite costly. It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key when needed.
A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. It is also able to copy the information from an existing key which allows duplicate keys to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with the computer, and they also have bidirectional interfaces to work with the immobilizer system.
There are a variety of keyprogrammers on the market. They come in all sizes, shapes, and colors. Some are cheap while others are sophisticated and can cost thousands of dollars. Some are specifically designed for certain types of cars and provide advanced diagnostics for your electronic systems of the car.
Consult your owner's guide to learn how to program a key for your vehicle. Certain manufacturers employ proprietary technology that makes sure that the dealership is the sole entity that can make new keys, however other manufacturers make it easy for anyone to do it on their own.
If you're unable to program a new key yourself, you can ask the dealership to do it for you, but this can be expensive. Another option is to buy a keyprogrammer online. They're less expensive than visiting a dealership but they aren't cheap. Before buying one, do some research on the seller. Some aren't trustworthy and could damage your vehicle.
Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's a small plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electro-magnetic field the chip emits a low level signal. This signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from being started by either hot-wiring or by tampering. The chip in the car key confirms that the owner is the person who is the owner of the vehicle. This will help reduce car theft.
Transponder keys look like normal keys but have a plastic cap. The chip is housed in the plastic portion of the key, and there are a few different cuts that can be found on the keys: a standard cut laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer onboard the car detects the signal as being correct it will turn off the car immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from attempting to alter the vehicle, however it is not a foolproof security measure. A determined and skilled thief could still bypass this system using a special device that detects the signal.
As you can see there are quite a few advantages to getting a transponder key. All car owners should consider this in order to safeguard their investment and reduce theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find the car in a parking lot keys of today can also switch on the heated steering wheel or open all windows with a single button press. These additional features can make it difficult for you to locate your car keys.
Key fobs communicate with one other and with the car through radio frequencies that are transmitted via an antenna that is located in the middle of the key. The signal is encrypted to stop others from stealing or stealing the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make of your vehicle. Certain cars let you do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a replacement key fob, or an alternative one.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the car with which it is paired. The receiver compared this information to the 'allowed' signals on the fob and either opens or locks the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to function.
Once the car is paired with a specific fob, it can only receive signals from the device. As a result, other fobs won't be able to work with the vehicle even though they have the same appearance. This helps to protect the integrity of the car's computer system and prevent unauthorized key fobs from gaining control over the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security skills which can only be obtained in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
